I'm at the dealer now, for two recalls, one for the integrated trailer module loss of communication (26C10), and one for the Powertrain control module PCM software update (26E01).

The Powertrain update/recall has been pushed out to October and it "might" be an OTA update when it's rereleased. I got a printout from the tech, "Please do not proactivly reach out to customers regarding this FSA until the OTA software deployment is completed (estimated October 2026)."

So I'm having 26C10 applied and I'm buying an intermediate steering shaft while I'm here. I'll have the part on-hand and can inpect/install when I have time. They wanted to charge $200 to diagnose the knock in the steering linkage...I said "nope" I'll just buy the part and install it when I get around to it - no need to diagnose anything.

 

Oddly, my experience was just the opposite. The dealer installed 26E01, which hit the PCM and TCM. Id honestly be surprised if they did those modules OTA, as an error could leave you stranded. They also appeared to have done a stationary region as well, as my MTE was 900+ miles when dropped off, and 450+ when I got it back. Maybe this flash removed the Limp mode for low def? Then for 26C10, I got the notice for this the very next day on the Ford app, and it says that it will come OTA at some point, but if towing, then have it done at the dealership immediately.

 

Well I can happily say that still, neither 26E01 or 26C10 has showed up in my Ford app! I still only have 22E04 that came out in June 2023, which is also an emission recall, same as the 26E01. Kind of makes me wonder if the 26E01 is the same as the 22E04, but for newer vehicles (mine is a 22).

Just my 2 cents, but I would still be leery of getting an emissions recall done that presents no information as to what it actually does or why they are doing it... Being an emissions recall, it should be good for however far down the line you want to get it, so when/if information finally comes out we can be better informed as to whether or not we want it. I am also curious if it is the DEF thing, but if so, why not just state that is what it is for... many of us would like that, but this may not be it. I also find it odd that some folks are saying they got it done while others say it's being put off... makes me wonder if the dealerships know what they are doing, and what they are actually doing... Sounds like they can't figure out what they are doing, so not sure I want them doing anything to my truck that is working great! Ah well, at least neither has popped up in mine so I don't have to wonder about it yet. And maybe that's because I haven't done the previous update either... lol.

 

Update: I waited in the lobby and did alittle work from there. They went ahead and applied both updates after the tech checked with Ford. And I bought the steering shaft outright, so I'll replace that at some point. Everything needed to be reset, menus, sound settings, nanny settings - it was all set back to default. So that took alittle time, but it seems like everything is fine and running well. Only time and mileage will tell. No more active recalls in the Ford pass app. I also changed the oil, rotated the tires, and fill the def tank last week - so I'm ready for spring in TX.

 

I did the first tow today after having 26E01 performed. No issues encountered, and the problem with the diesel gauges not being available in the cluster with a trailer attached has been fixed - probably due to a cumulative nature of updating the offending modules.

 

Not to split hairs here, but the 26E01 recall you're referring to relates to a PCM update, not a Tow mode issue. Did your (F250?, YR Model?))also receive the 26C10 update which does relate to the Tow mode update?

 

2024 450 - and no, the 26C10 update is still outstanding. The 26E01 touches PCM and TCM both according to the tech that ran the update. I can confirm that prior to the recall being performed the diesel gauge screen was not available when a trailer was connected, and after it is now present. While the actual recall is not related, updating one of those modules addressed the issue, so either the updates are cumulative or any additional updates available ran at the same time.

 

Its all rather confusing. At one time the PCM recall was described as an emissions update. Ford has changed that.
This is the Canadian VIN recall search for my truck (disappointingly little information):


USA results attached as pdf's below.

Until I hear otherwise I'm going to assume some admin at Ford mistakenly used the word emissions in the recall title that has since been corrected, and both recalls are about getting the appropriate modules to play nice with each other once the trailer module communication glitch is corrected, but who knows!
26E01 doesn't mention OTA updates implying the PCM should be done by the dealer. 26C10 mentions OTA.

 

Mobile tech came out yesterday and installed the 26C10 and 26E01 updates. Other than one configurable guage changing on the dash, I haven't noticed any changes and the truck hasn't exploded. Ford app also now shows zero active recalls.

 

Finally had this start popping up on the Sync screen everytime I start the truck. Opening the Ford App, ( I have auto updates off) this screen appeared. No way I'm going to induce a possible 45 minute out of service ( or brick condition) while 1,000 miles from home. Going to ignore it for now, but very interested in reading about others experiences with this update, both positive or negative. Can't put model info in a sig line that I can see. 2026 F550 7.3L gas.

 

I just had this recall as well as the Trailer module one, 26c10, done this morning. The only thing that I noticed is the screens I had selected changed to default ones. The 26E01 may be nothing more than what was done to the F150 last year where updates to engine self diagnostics were made and that was considered an emissions change.

 

it isn’t super intuitive but the tow haul mode settings are in a different menu which allows you to customize what is on the left part of the screen. I think by default it goes to trailer data.

 

That is a different display. What was not working for at least some MY24 trucks was the diesel gauge screen - values for exhaust brake and turbo, etc. when a trailer was connected. The screens were available but blank. Disconnect the trailer and *poof* they populated again. This was addressed with an OTA that I never got, but they worked correctly on my last 2 trips since having this particular update performed.

 

I had both 26E01 & 26C10 completed last week. All works as expected.

 

What is your truck's year, model, gas or diesel? Thx
